| Definitionskos:definition | The Testbed-11 deliverable OGC 15-053 Implementing JSON/GeoJSON in an OGC Standard ER enumerated strategies for implementing JSON in OGC services and OGC encodings. Previously, a mechanism to migrate XML into JSON was proposed by Pedro Gonçalves in 14-009r1 OGC Testbed-10 Rules for JSON and GeoJSON Adoption: Focus on OWS-Context. In contrast, this engineering report (ER) proposes a mechanism to derive JSON and JSON-LD encodings from UML modeling without using XML as an intermediate step. The rules provided can be divided into rules for JSON instances and rules for JSON schemas. These rules have been applied to the UML diagrams in OWS common 2.0 to derive JSON encodings for them. In practice this ER evaluates how to provide service metadata in the derived JSON. JSON schemas and @context documents for independent validation of the four main sections of the ServiceMetadata are provided. This activity is done in connection with the OGC 16-052 OWS Context / Capabilities ER. The rules are applied to WMS to provide a full JSON encoding for the WMS 1.4 standard candidate. Finally, this ER discusses the applicability to data geospatial formats, both for coverage formats (compared to the CIS standard) and feature formats (compared to GeoJSON). Readers unfamiliar with JSON, JSON-LD and JSON Schema should first read OGC 16-122 (Geo)JSON User Guide. OGC 16-122 includes guidelines and recommendations for the use of JSON and JSON-LD in OGC data encodings and services. |
